Reactionless drive is nothing to do with exhaust
I hope I am using this page correctly. The statement that a reactionless drive does not involve the exhaust of a propellent is questionable, bordering on misleading, I'm afraid. The mention of Newton's Third Law is highly relevant and accurate but an exhaust (produced by a propellent) is only relevant in the case of a rocket- or jet engine. Reaction can be produced by other mechanisms; for example, the action of pushing an object/vehicle along the ground produces the reaction of pushing the ground in the opposite direction. In the case of space travel (probably the only practical application of a reactionless drive) the source of power is a side-issue but could conceivably produce an exhaust. I offer this comment in hope that it will clarify an otherwise interesting entry. My suggestion would be "...producing motion without exerting force at 180 degrees to the direction of travel".

Chislehurst & Sidcup Grammar School
A few weeks ago I offered some insights on 'Dick' Pedley, former headmaster of Chis & Sid. The edits were deleted and I would like to know on what basis they infringed any policy or rule pertaining to the page. In my ignorance I believed that a Wiki article could be edited (obviously with good intent) by anyone. My contributions were wholly accurate and true, as I was a pupil at the school in the 1970s. I'd be glad to join a discussion on the matter in case I can offer any further information. The business of using these Talk pages is new to me and confusing. If I am not using the facility correctly, I'd welcome advice on the subject. Modelmaniac99 (talk) 16:55, 15 August 2018 (UTC)Ian
 * You need to post on the talk page of the article you want to be changed. (For your second comment this would be Talk:Chislehurst and Sidcup Grammar School).  Most editors aren't going to read your comments here, and for your first comment I don't know what page you are referring to. LynxTufts (talk) 20:13, 15 August 2018 (UTC)
